TAMPA — Supporters of presidential candidate Ron Paul are negotiating to hold a three-day festival of music, entertainment and activism at the Florida State Fairgrounds immediately before the Republican National Convention.

Paul Festival 2012 would run from Aug. 24-26, ending the day before the convention begins.

Details like ticket prices and who would be on stage have not been announced, but the festival could draw 20,000 or more people a day, estimated Deborah Robinet, an organizer who lives near San Diego .

“Ron Paul supporters are very enthusiastic, and there’s going to be a bunch of them in Tampa,” said Robinet, one of five directors of the nonprofit group Liberty Unleashed, which was incorporated this month in Florida to make arrangements for the festival.
